Reference to "Umwelt ethics" in Uexküll framing essay

My 2003 article "Umwelt ethics" is referred to in the article Jonathan Beever and I co-wrote as a framing essay to the translation of an 1917 essay by Jakob von Uexküll. Reference:

Beever, Jonathan and Morten Tønnessen 2013. “Darwin und die englische Moral”: The Moral Consequences of Uexküll’s Umwelt Theory. Biosemiotics 6(3): 437–447 (online version published September 25 2013, DOI 10.1007/s12304-013-9180-x).

The reference is made on p. 441, in this sentence:

Following Uexküll’s lead in extending consideration to a wide host of nonhuman organisms, a small but growing number of philosophers and semioticians have begun exploring whether and to what extent Umwelt theory might inform animal and environmental ethics, the study of the scope and nature of moral value in the living world (Hoffmeyer 1995; Tønnessen 2003; Kull 2001; Champagne 2011; Beever 2012; Acampora 2013 etc.).

Uexküll translation project in process; deadline extended to February 28th

In March 2012 Jonathan Beever and I agreed with Editor-in-Chief of Biosemiotics Marcello Barbieri that the two of us will translate Jakob von Uexküll's 1917 essay "Darwin und die Englische Moral" and write a framing essay to go along with it. More specifically, I will do the translation, with language editing done by Jonathan. The framing essay will be co-written by both of us.

We originally planned to have the texts done in the autumn of 2012, but before Christmas got acceptance for a delayed deadline, February 28th 2013. However, we have by now started on both the translation and the framing essay, and have agreed to maintain regular contact, with Skype calls approximately every second week, in January and February (and beyond that as well, due to another, thematically related writing project).
